+/**
+ * board_init_f_mem() - Allocate global data and set stack position
+ *
+ * This function is called by each architecture very early in the start-up
+ * code to set up the environment for board_init_f(). It allocates space for
+ * global_data (see include/asm-generic/global_data.h) and places the stack
+ * below this.
+ *
+ * This function requires a stack[1] Normally this is at @top. The function
+ * starts allocating space from 64 bytes below @top. First it creates space
+ * for global_data. Then it calls arch_setup_gd() which sets gd to point to
+ * the global_data space and can reserve additional bytes of space if
+ * required). Finally it allocates early malloc() memory
+ * (CONFIG_SYS_MALLOC_F_LEN). The new top of the stack is just below this,
+ * and it returned by this function.
+ *
+ * [1] Strictly speaking it would be possible to implement this function
+ * in C on many archs such that it does not require a stack. However this
+ * does not seem hugely important as only 64 byte are wasted. The 64 bytes
+ * are used to handle the calling standard which generally requires pushing
+ * addresses or registers onto the stack. We should be able to get away with
+ * less if this becomes important.
+ *
+ * @top:	Top of available memory, also normally the top of the stack
+ * @return:	New stack location

+/**
+ * arch_setup_gd() - Set up the global_data pointer
+ *
+ * This pointer is special in some architectures and cannot easily be assigned
+ * to. For example on x86 it is implemented by adding a specific record to its
+ * Global Descriptor Table! So we we provide a function to carry out this task.
+ * For most architectures this can simply be:
+ *
+ *    gd = gd_ptr;
